# Mellow AI > Mellow AI is an independent AI engineering studio in Dallas, Texas, working remotely with clients worldwide. We design and ship production AI systems — document extraction, agents, evaluation, and the infrastructure underneath — and the client owns every piece: code, models, infrastructure, and operating knowledge. Mellow AI does not sell a platform and does not resell a license. Engagements are staffed by small senior teams that build inside the client's own environment rather than a demo sandbox, and everything built is handed over. Typical work: custom AI systems, agent and tool-use architectures, LLM deployment, document and data extraction, evaluation harnesses, model fine-tuning, AI project rescue, and production infrastructure. Built with TypeScript, Python, and Rust on Next.js, the Vercel AI SDK, pydantic-ai, Postgres, Zod, and the Model Context Protocol. Model choice is deliberately portable across providers. Based in Dallas, TX. Working worldwide.

Email info@staymellow.ai or use the form. - [MCP server](https://staymellow.ai/mcp): Connect an agent to Mellow AI over the Model Context Protocol. ## Open source we build and maintain - [openextract-ts](https://mellow-artificial-intelligence.github.io/openextract-ts/guide.html): TypeScript toolkit that takes a document, image, audio, or video file to a validated Zod object in one call, with a model swarm that reconciles several reads by merge, vote, or first success. Ships an MCP server, a CLI, a terminal UI, and a local web cookbook. - [openextract](https://mellow-artificial-intelligence.github.io/openextract/): Python toolkit that turns documents, images, audio, and video into validated Pydantic models in one function call, across 11 model providers via pydantic-ai. - [Open Lease Audit](https://github.com/colesmcintosh/open-lease-audit): Portfolio integrity console for commercial leases: user-defined extraction schemas, one streaming abstraction per lease, then a cross-lease reconciliation pass that ranks findings by severity. - [pdfmd](https://colesmcintosh.github.io/pdfmd/): Zero-dependency Rust PDF-to-Markdown converter. The object-graph reader, DEFLATE decoder, font decoding, and column and table heuristics all live in the crate — roughly 3,900 pages per second. ## Services - Custom AI system development: Production AI systems designed around a specific problem and shipped into the client's own environment — not a template, a demo, or a wrapper around someone else's product. - AI agent engineering: Agent and tool-use architectures with real evaluation, tracing, and guardrails, built on the Model Context Protocol and the Vercel AI SDK. - Document and data extraction: Schema-driven extraction from documents, images, audio, and video, with per-field confidence and a verbatim source clause behind every value. - LLM deployment and infrastructure: Model routing, provider portability, caching, cost controls, and the production infrastructure underneath an AI product. - AI evaluation and observability: Evaluation harnesses and regression suites that tell you whether a change to a prompt, a model, or a retrieval step actually made the system better. - AI project rescue: Diagnosis and repair of AI builds that stalled — prototypes that never reached production, systems that degraded, or vendor work that has to be taken over. ## For agents - [MCP endpoint](https://staymellow.ai/api/mcp): Streamable HTTP.
